derivative of-2y

derivative of

- 2 y

- 2

Solution steps

\frac{d}{d y} (- 2 y)

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - 2 \frac{d y}{d y}

Apply the common derivative:

\frac{d y}{d y} = 1

= - 2 \cdot 1

Simplify

= - 2

t an g e n t f (x) = 5 e^{x} + x, (0, 5)

x \to b lim (\frac{x - b}{x - b})

\frac{\partial}{\partial y} (\frac{1}{y})

x \to 1 lim (cos (\frac{1}{x - 1}))

t an g e n t y = x^{3} - 3 x + 3, (3, 21)
